6 Lone Star Ore Body Development Project EIS Introduction The U.S. Army Corps of Engineers (Corps) Los Angeles District is examining the environmental consequences associated with the application from Freeport-McMoRan Safford Inc. (FMSI) for a Department of the Army permit under Section 404 of the Clean Water Act (CWA) for the proposed development of the mineral resources associated with the Lone Star ore body for the purpose of producing copper (the Lone Star Project). The proposed development would be the construction of mining facilities, including an open pit mine and attendant development rock stockpiles and heap leach facilities, which will allow continued mining at the Safford Mine Facility using conventional open pit mining, heap leaching techniques, and solution extraction/electrowinning processing, and utilizing as much of the existing Safford Mine Facility infrastructure and processing facilities as practicable. The construction of the proposed facilities would discharge fill materials into approximately acres of Waters of the United States (U.S.). The primary federal environmental concerns are the proposed discharges of fill material into waters of the U.S. and the potential for significant adverse environmental effects resulting from such activities. Therefore, to address these concerns in accordance with the National Environmental Policy Act (NEPA), the Corps is requiring preparation of an Environmental Impact Statement (EIS) prior to consideration of any permit action. The action must comply with the section 404(b)(1) Guidelines (40 Code of Federal Regulations [CFR] part 230) and not be contrary to the public interest to be granted a Corps permit. The Corps may ultimately make a determination to permit or deny the above project, or permit or deny modified versions of the above project. Two primary principles of the NEPA are full disclosure of potential environmental effects and open public participation throughout the decision-making process. Through the public involvement process, the public is able to participate in the NEPA process. NEPA requirements for public involvement are set forth in Council on Environmental Quality (CEQ) regulations 40 CFR This Scoping Summary Report provides an overview of the public scoping process and a summary of the scoping comments, issues, and concerns identified during public scoping. Although the Corps encourages commenting on the Project throughout the preparation of the Draft EIS, the range of issues summarized in this report is based on the comments received during the public scoping period. 1.1 Purpose of Scoping The purpose of the public scoping process is to identify issues and planning criteria that should be considered in the Draft EIS and to initiate public participation in the planning process. The Corps follows the public involvement requirements according to the CEQ regulations set forth in 40 CFR , which states, there should be an early and open process for determining the scope of issues to be addressed and for identifying the process for determining the scope of issues to be addressed during the planning process. The scoping process is open to all interested agencies and the public. The intent is to solicit comments and identify the issues that help direct the approach and depth of the environmental studies and analysis needed to prepare the Draft EIS and incorporate the views and concerns of federal, state, and local agencies, as well as the public, regarding the scope of issues to be analyzed in the EIS. Other objectives of scoping include: Identifying and inviting agencies with jurisdiction or special expertise relevant to the Proposed Action and alternatives to participate in the NEPA process as cooperating agencies; Identifying other environmental review and consultation requirements; Identifying the relevant and substantive issues that need to be addressed in the EIS analyses; Determining the range of alternatives to be evaluated; and Developing the environmental analysis criteria and systematic planning process and allocating EIS assignments among agencies as appropriate.

7 Lone Star Ore Body Development Project EIS Document Organization This document contains summary descriptions of the: Scoping process, including scoping meetings, advertising leading up to the meetings, and opportunities for public comment during the scoping period (Chapter 2.0); Scoping content analysis process, including how individual letters and comments were coded and tabulated (Chapter 3.0); Comments organized by resource (Chapter 4.0); Issues raised by public comment (Chapter 5.0); and Next steps in the EIS process (Chapter 6.0). All comments were given equal consideration, regardless of method of transmittal.

8 Lone Star Ore Body Development Project EIS Scoping Process This chapter provides a description of the scoping process, the means by which the public and agencies were notified and given opportunities to comment on the Lone Star Project, and a brief summary of the meetings that were held. 2.1 Federal Register Notice of Intent The scoping comment period began January 5, 2015, with the publication of the Notice of Intent (NOI) to prepare an EIS in the Federal Register (Vol. 80, No. 2, pages 212 to 213). The NOI notified the public of the Corps intent to prepare an EIS for the Lone Star Project and the beginning of a 45-day scoping period. The Corps also posted the NOI on the project website ( A copy of the NOI is provided as Appendix A. 2.2 Public Notification of Permit Application and Public Scoping On January 5, 2015, the Corps posted on its website Public Notice SPL MWL, Receipt of Application for a Corps Permit, Notice of Intent to Prepare a Draft EIS and Hold a Public Scoping Meeting for the Lone Star Ore Body Development Project. The notice indicated that FMSI had applied for a Section 404 permit, provided project information and invited the public to comment on the project. The notification indicated that the comments would be used in preparation of an EIS. The notification also provided the date and time of the public scoping meeting, and identified February 20, 2015 as the close of the scoping comment period. The Corps published four newspaper display advertisements providing information on the public scoping meeting. Ads were published in the Apache Messenger and Eastern Arizona Courier on January 21, and 28, Copies of the public notice and a sample newspaper advertisement are included in Appendix B. 2.3 Scoping Meetings The Corps hosted one scoping meeting on February 4, 2015 in Safford, Arizona. The meeting provided an opportunity for the Corps to inform those in attendance about the Proposed Action and alternatives and the EIS process and to solicit input on the scope of the analysis and potential issues. The meeting was held from 6:00 p.m. to 9:00 p.m. The 3-hour meeting comprised an open house with a 30-minute presentation at 7:00 p.m. Attendees were greeted, asked to sign in, given a comment form, and informed about the meeting agenda, the general flow of information (display boards) in the room, and ways to submit comments to the Corps. Informational display stations positioned around the meeting room described the project and environmental resources in the project area, and outlined the CWA Permitting and NEPA processes scoping process, described the type of comments most useful to the Corps, and provided methods and deadlines for comment submittal. Technical experts from the Corps and FMSI were present to answer questions about the project. The Corps presented a PowerPoint slideshow with information on the background information about the proposed project and information about the Corps permitting and EIS processes, and methods for public comment.

9 Lone Star Ore Body Development Project EIS 2-2 Copies of the display boards, presentation, and the comment form are provided in Appendix C. 2.4 Opportunities for Public Comment Members of the public were afforded several methods for providing comments. Comments could be recorded on comment cards at the scoping meeting. s could be sent to the Corps Project Manager s address: Michael.W.Langley@usace.army.mil. Letters could be mailed to: U.S. Army Corps of Engineers, Los Angeles District, Arizona Regulatory Branch, Attn: SPL MWL, 3636 N. Central Ave, Suite 900, Phoenix, Arizona

10 Lone Star Ore Body Development Project EIS Scoping Content Analysis Upon receipt, all contact information for all submittals was entered into the comment database and project mailing list (unless there was a specific request for contact information not to be included), along with the submittal method and entity/affiliation of each submittal. Each submittal was labeled with a numeric identifier, and was reviewed to capture both submittal-level and specific comment level information. 3.1 Submittal-level Coding Each submittal was reviewed as a whole to specifically identify the following submittals. Out-of-scope submittals: those submittals that did not pertain to the Lone Star Ore Body Development Project at all (for example, a submittal pertaining to another project or seeking employment). Submittals requiring immediate attention, such as submittals containing requests for maps or other data; official Freedom of Information Act requests; requests for comment period extension; or other comments that needed to be brought to the attention of the Corps immediately. Form letters (standardized and duplicated letters that contain the same text or portions of text and comments) and form pluses, which are form letters that have been modified to contain additional unique comments. As shown in Table 3-1, the Corps received a total of 12 unique submittals. No out-of-scope, immediate attention, form letters or form-plus submittals were received. Method of submission to the Corps was fairly evenly divided between the three submittal options. Table 3-1 Submittal Summary by Method Code Submittal Method Number of Submittals E 4 M Comment submitted at meeting 4 L U.S. Postal Service letter 6 Total 14 Table 3-2 shows the affiliation of each commenter. Contact information was gathered for all submittals. Appendix D provides a list of individual commenters and their affiliations.

Each submittal contained one or more comments, and each comment was categorized and coded by primary resource issue or topic. Comments were assigned a general code corresponding to their respective resource issue or topic (for example, WL for wildlife), and a numeric sub-code specific to that resource to further group similar comments (as an example, comments suggesting wildlife existing condition data that should be used in the EIS were coded as WL-2 ). This form of analysis is used to allow resource specialists to view public concerns by general resource issue as well as resource-specific topics. In some cases, comments were given codes for a second primary resource; for example a comment about erosion affecting streams might be given primary resource issue or topic codes (and appropriate subcodes) for both soils and water resources. A total of 172 comments were identified and coded. Of this total, 46 comments also were coded to a second primary resource, for a total of 188 comments to be considered in the following resource summaries (Table 3-3). Figure 3-1 graphically identifies the percentage of comments by general resource issue or topic.

14 Lone Star Ore Body Development Project EIS Substantive Public Comment Summary Substantive scoping comments fell into the following four broad categories: Process, Purpose and Need, Alternatives Development, and Impacts Analysis (including resource-specific concerns and cumulative impacts). Comments are summarized below in narrative form for each resource issue area (e.g., all comments specific to wildlife are included under the Wildlife category; all comments specific to visual resources are in the Visual Resources category, etc.). This section represents a summary of the formal comments received during public and agency scoping. A more detailed record of all unique comments is included as Appendix E. The narrative summary is organized in the following order, which generally mirrors where the comments would be addressed in the resulting Draft EIS. Process (Chapters 1.0 and/or 6.0 of an EIS). Purpose and Need (Chapter 1.0 of an EIS). Alternatives (Chapter 2.0 of an EIS). Impact Analysis (Chapters 3.0 and 4.0 of an EIS), organized by resource type (Physical Resources, Biological Resources, and Human Resources) and followed by general cumulative impacts and mitigation comments and other comments that do not fit other resources categories). Non-substantive comments, including statements of support for lease reaffirmation and statements of opposition to lease affirmation. 4.1 Process CWA 404 Permitting Process Comments requested that the Draft EIS describe the CWA Section 404 permitting process and the status of the project in that process. The Environmental Protection Agency (EPA) indicated that pursuant the1992 Memorandum of Agreement between the USEPA and Department of the Army regarding CWA Section 404, the USEPA has identified the Lone Star permit action as a candidate for review by USEPA and Corps headquarters. The USEPA provided instruction for Draft EIS submission Coordination with Other Agencies and Other Permitting Processes Comments suggested that the project also may require coordination with the following agencies. Office of Surface Mining (permits needs not described). State Historic Preservation Office (also see Section 4.4.7, Cultural Resources). Arizona Department of Agriculture (coordination per Arizona Native Plant Law and Antiquities Act; also see Section 4.4.5, Vegetation Resources). Arizona Department of Environmental Quality (ADEQ) (water quality permitting; also see Section 4.4.4, Water Resources). Arizona Department of Water Resources (water quality permitting; also see Section 4.4.4, Water Resources). Arizona Game and Fish Department (AGFD) (coordination regarding wildlife and in particular, bats; also see Section 4.4.6, Wildlife). U.S. Fish and Wildlife Service (USFWS) Ecological Services Offices (consultation per the Endangered Species Act; also see Section 4.4.6, Wildlife).

15 Lone Star Ore Body Development Project EIS 4-2 Comments requested that the EIS describe all permits and permits requirements that apply to the project. The AGFD requested cooperating agency status, and proposed communication on an ongoing basis rather than just during formal comment periods. They AGFD suggested that they should be a resource for both nongame and threatened and endangered wildlife and requested participation in the Section 7 consultation. The AGFD also requested specific review periods for Administrative Draft EIS and Draft EIS Government-to-Government and Section 106 Consultation Comments cited an April , presidential memorandum and Executive Order (EO) (2000) as containing the principles guiding formal government-to-government consultation with Native American tribal governments and recommended that the EIS discuss the Corps consultation with all tribes potentially affected by the proposed project or may have resources (e.g., traditional cultural properties, groundwater resources, etc.) that could be affected by the project. Comments recommended that consultation take place early in the scoping phase of the project to ensure that all issues are adequately addressed in the EIS, and indicated that efforts should be made to avoid or mitigate impacts to culturally significant sites. No official Government-to-Government Consultation requests were received from tribes during scoping; however several tribes requested consultation and coordination with the Corps during the EIS process. Respondents specifically suggested coordination with the San Carlos Apache Tribal Council and noted that the proposed project area is within the ancestral lands of the Four Southern Tribes (Gila River Indian Community; Salt River Pima-Maricopa Indian Community; Ak-Chin Indian Community and the Tohono O'Odham Nation). The Gila River Indian Community Tribal Historic Preservation Office (THPO) indicated they would participate as a consulting tribe for this undertaking. The White Mountain Apache THPO requested the Cultural Survey report conducted for the project. The San Carlos Apache Tribe indicated that they requested the Cultural Survey report conducted for the project and requested that the Corps contact them to clarify potential impacts to cultural and water resources Public Involvement Comments noted that EO requires consideration of the disproportionate adverse impacts of federal actions on minority and low-income populations and indicated the Corps should present opportunities for affected communities to provide input into the NEPA process. 4.2 Purpose and Need Comments stated that the EIS needs to adequately identify and describe the underlying need(s) for the project and the associated objectives or outcomes for purposes of both the NEPA analysis and the CWA Section 404(b)(1) alternatives analysis. 4.3 Alternatives Proposed Action Comments requested the following types of information related to FMSI s Proposed Action, including the following. Potential water sources and the amount of water needed for the project. Inclusion of best available demonstrated control technology to be used to Arizona groundwater standards.

16 Lone Star Ore Body Development Project EIS 4-3 Procedures for how waste rock (or development rock) will be handled, disposed, and reclaimed at the mine, including how potentially acid generating material would be encapsulated or intermixed to prevent the development of seepage with adverse water quality, as supported with geochemical testing data and on-site current or historic monitoring data (existing seepage water quality, on site pan evaporation rates, documentation of the successful closure of some existing facilities, etc.). Facility designs and control measures to ensure against leaching and release of contaminants under both acidic and non-acidic conditions, and degradation of surface water and groundwater quality. Procedures outlining how accidental releases of hazardous materials would be handled. A petroleum-contaminated soil management plan. A comprehensive reclamation plan that includes: A detailed account of measures that would be taken to decommission mine operations and stabilize and revegetated slopes, waste rock facilities, heap leach pads, roads and other areas (also see Section 4.4.5, Geology and 4.4.6, Water Resources); Estimated acreage and areas targeted for reclamation, and description of the intended degree of treatment in each area; Timing of reclamation relative to mining operations, procedures for concurrent reclamation activities, and duration of reclamation treatment; Standards for determining and means of assuring successful reclamation; and Commitments by the mine company and agencies regarding operation and maintenance of caps/covers, draindown systems and any proposed evapotranspiration cells, fencing and wildlife protection measures, diversion channels, underdrain systems, wells, and other elements of the plan. Respondents also stated that the Proposed Action should clearly identify any connected actions Action Alternatives Comments stated the EIS should explore and objectively evaluate all reasonable alternatives, including reasonable alternatives not within the jurisdiction of the Corps. Respondents suggested that reasonable alternatives could include, but are not necessarily limited to alternative designs or methods, smaller projects, and a reconfigured project design. The AGFD requested to participation in the alternatives development process Alternatives Eliminated Comments stated the EIS must include a rationale for the elimination of any alternatives that were not evaluated in detail. 4.4 Impact Analysis Comments stated that the alternatives analysis must assess the direct, indirect and cumulative impacts from the proposed project. Respondents stated that the EIS should disclose potential environmental impacts of the alternatives in comparative form, thus sharply defining the issues among the options for decision makers and the public. Comments indicated that the EIS must identify the Least Environmentally Damaging Practicable Alternative and disclose if the alternatives meet any of the other restrictions on discharges, including the

17 Lone Star Ore Body Development Project EIS 4-4 need to ensure appropriate compensatory mitigation for unavoidable impacts. Comments suggested the Corps should only select the Least Environmentally Damaging Practicable Alternative. Respondents indicated that the EIS analysis should include closure and post-closure activities associated with the tailings, heap leach pad, waste rock piles, and other facilities, including implementation, performance, and effectiveness monitoring, and follow up actions that would be taken should destabilization or contamination be detected Air Resources, including Climate Change Comments indicated that the EIS should include a robust analysis of the project s potential to affect air quality National Ambient Air Quality Standards and Prevention of Significant Deterioration Comments expressed concern about impacts to of National Ambient Air Quality Standards (NAAQS) and Prevention of Significant Deterioration (PSD) elements and requested that that the EIS include the following. Descriptions of existing air quality in the project vicinity. Discussions of the NAAQS and PSD increments applicable to air quality in the project area. Comments noted that PSD increments exist for sulfur dioxide, nitrogen dioxide, and Particulate Matter smaller than 10 microns in diameter (PM 10 ), and PM 2.5 (particulates smaller than 2.5 microns in diameter). Identification of all Class I PSD areas located within 100 kilometers of the proposed project site. Comments stated that the Corps should consult with the U.S. Forest Service and National Park Service for a determination of which areas could be adversely affected by the Proposed Action. Summaries of project emissions from all facilities and roads related to the mine s operations, including any off-site processing and support activities, such as vehicle traffic and delivery trucks for fuels, maintenance supplies, and other materials. Consideration of cumulative emissions from other sources in the project area, including existing facilities and ongoing operations associated with the Dos Pobres and San Juan pits; Modeling to determine concentrations of criteria air pollutants for an accurate comparison with the NAAQS. The air quality analysis presented in the EIS should demonstrate that new emissions emitted from the proposed project, in conjunction with other applicable emissions increases and decreases from existing sources, will not cause or contribute to a violation of any applicable NAAQS or PSD increment. Discussions of potential impacts to Class I PSD areas, including visibility impacts. Potential for fugitive dust, especially dust that contains toxins, abrasives, or otherwise ecologically disruptive compounds. Respondents indicated that the EIS should discuss mitigation measures to minimize air pollutant emissions from the mine, and include measures to address potential impacts to nearby residents, including sensitive receptors. Comments suggested that diesel particulate matter (DPM) and other criteria pollutants from fugitive sources at the mine could be reduced by implementing appropriate mitigation measures, such as: Using particle traps and other appropriate controls to reduce emissions of DPM and other air pollutants; Minimizing construction-related trips of workers and equipment, including trucks and heavy equipment;

18 Lone Star Ore Body Development Project EIS 4-5 Leasing or buying newer, cleaner equipment (1996 or newer model); and Employing periodic, unscheduled inspections to ensure that construction equipment is properly maintained at all times and does not unnecessarily idle, is tuned to manufacturer's specifications, and is not modified to increase horsepower except in accordance with established specifications. Comments also stated that EIS should discuss whether and how air quality monitoring would be implemented to ensure project compliance with all applicable air quality standards and permits Hazardous Air Pollutants Comments related to hazardous air pollutants (HAPs) indicated the EIS should list in detail all possible sources of HAPs and the unit processes that generate this material; estimate releases of HAPs from the proposed project to air, soil, and water resources; and describe the HAPs monitoring that would be conducted, including locations and reporting requirements. Respondents stated the EIS should discuss how all HAPs would be controlled to reduce their emissions as much as possible, including from any offsite facilities that will process ore from this project, and that the EIS should describe the equipment included in the system to condense, capture, and/or treat HAPs and reduce their emissions and disclose the effectiveness of these measures in removing HAPs and making it unavailable for release into the environment Greenhouse Gases Comments stated that the analysis of greenhouse gases (GHGs) and climate change should be consistent with new CEQ draft guidance provided in December 2014, which indicates that impact analysis should consider both the potential effects of a Proposed Action on climate change as well as the implications of climate change. Respondents also noted that the revised draft guidance suggests that if an agency determines that evaluating the effects of GHG emissions would not be useful in the decision making process and to the public to distinguish between the Proposed Action, alternatives and mitigations, the agency should document the rationale for that determination. Comments recommended that sustainable design and operation measures that reduce greenhouse gases be identified in the EIS with an estimate of the greenhouse gas emissions reductions that would result if these measures were implemented. Respondents suggested the following mitigation measures to reduce GHGs. Using conveyors rather than haul trucks where possible, e.g., for transporting ore to processing areas and the heap leach facility. Incorporating alternative energy components into the project such as on-site solar and/or geothermal power generation. Offering ride sharing or shuttle opportunities for mine employees commuting to the site from both nearby and distant communities. Committing to using high efficiency diesel particulate filters on new and existing diesel engines to provide reductions of black carbon emissions. Comments stated the EIS should then clearly indicate whether these measures would be required and explain the quality of each mitigation measure, including its permanence, verifiability and enforceability Geological Resources Comments related to geological resources focused solely on geochemistry and stated that accurate characterization of the mine s geochemistry would be critical in identifying the project s potential for leaching and release of contaminants and indicated the EIS should include the following information.

19 Lone Star Ore Body Development Project EIS 4-6 Descriptions of the static and humidity cell tests that have been conducted on ore and waste rock to characterize them, and a summary of the test results. Identification of how the geochemical testing procedures were designed to comply with all applicable guidance and industry standards. Descriptions how waste rock or development rock) will be handled, disposed, and reclaimed at the mine: Facility designs and control measures that would be implemented to ensure against leaching and release of contaminants under both acidic and non-acidic conditions, and degradation of surface water and groundwater quality; Whether a synthetic geomembrane cap will be required to prevent infiltration into heap leach, tailings or waste rock facilities. Cover design should be described in detail with supporting data to demonstrate anticipated effectiveness; and Process by which potentially acid generating material would be encapsulated or intermixed to prevent the development of seepage with adverse water quality, supported with both geochemical testing data and on-site current or historic monitoring data (existing seepage water quality, on site pan evaporation rates, documentation of the successful closure of some existing facilities, etc.). Comments stated that where existing waste rock and heap leach facilities can be reasonably used as analogs for the new or expanded facilities, such comparisons should be made and clear data should be presented for why the proposed designs would be more or equally successful in avoiding the production of adverse seepage water. Comments related to closure and post-closure activities associated with the tailings, heap leach pad, waste rock piles, and other facilities requested information regarding commitments by FMSI and agencies regarding operation and maintenance of caps/covers for heap leach, tailings or waste rock facilities Soils Comments stated that the EIS should include details regarding the mine s petroleum-contaminated soil management plan (also see Section 4.4.9, Hazardous Materials). Comments regarding project reclamation (also see Proposed Action, and Section 4.4.4, Water Resources) noted that reclamation and closure of the tailings, heap leach facilities and waste rock disposal areas would involve placing growth media over rock material to provide store-and-release covers for the purpose of reducing infiltration of meteoric water. Respondents stated that the EIS should describe the availability, properties, and sources of cover material and/or growth media (including the permeability standard that growth media or other cover material for the heap leach, tailings, and waste rock facilities would be designed to achieve, the basis for infiltration rates and cover/growth media thickness estimates) and discuss how it would be applied to disturbed areas. Comment stated the EIS must evaluate the effectiveness in minimizing exposure of mined material to meteoric water that could mobilize contaminants, and identify any additional measures (e.g., amendments) that may be needed to ensure successful reclamation and revegetation of the project site Water Resources General Concerns Comments expressed concern about impacts to water quantity and water quality for both groundwater and surface waters (wetlands, streams, springs, and/or riparian habitats). Comments related to water quantity stated the EIS should identify:

20 Lone Star Ore Body Development Project EIS 4-7 Potential water sources and the amount of water needed for the project; All potential project discharges, seepage, temporary ponding, surface water diversions, and groundwater pumping/dewatering; Potential impacts associated with using each proposed water source, including direct, indirect, and cumulative impacts to water rights, surface water flow, beneficial uses, and impacts to water supply wells, wetlands, springs and seeps, vegetation, wildlife, and other surface-or groundwater-dependent resources as a result of surface diversion or groundwater pumping associated with the proposed project; and Post-closure groundwater elevation recovery. Comments stated that headwater streams within the project area provide valuable surface water and groundwater recharge for the Gila River watershed. Comments also cited data showing that he Gila River hydrologic units provide approximately 35% of total surface water withdrawals for all water uses in Arizona and 37% of the surface water withdrawals used for irrigation. Comments expressed concern that groundwater pumping and interception of groundwater by the pit may cause a dewatering cone of depression around the mine and dewater springs, seeps, and similar features. Comments related to water quality expressed concern about: Impact to wetlands, streams, springs, and/or riparian habitats; Pollution from storm water runoff; Hazardous materials or pollutants entering the Gila river via ephemeral washes or other methods; Abandoned wells resulting in leaking into other wells that are currently in use; The potential for contamination of meteoric water that contacts existing and proposed waste rock, pit wall rock, heap leach, stockpiles, roads, and other mine facilities; and Potential for and effects of movement of any contaminated surface water to the subsurface, including through the pit bottom. Impacts to tanks and other water sources used by wildlife. Comments identified the Gila River as an aquatic resource of national importance (ARNI) and stated that given the ongoing open-pit mining operations in the Dos Pobres and San Juan pits, and the facility s proximity to the Gila River, it is critical that the EIS thoroughly analyze and discuss the proposed project s potential impacts upon water resources in the context of the impacts that have already resulted from past and current mining activity. Comments identified the importance of several riparian areas in and adjacent to the Gila River, including Coyote and Watson Washes and Bear Springs Canyon. The USEPA stated that impacts may contribute to the significant degradation of the Gila River, and thus may represent substantial and unacceptable impacts to an ARNI. Comments noted that the Gila Box Riparian National Conservation Area (GBRNCA) is located within two miles of the mine and includes four perennial waterways, the Gila and San Francisco Rivers and Bonita and Eagle Creeks. Comments expressed concern about the Bonita Creek watershed in particular, identifying it as a riparian s ecosystem with plant and animal diversity. The AGFD recommended early direct coordination with its Project Evaluation Program for projects that could impact water resources, wetlands, streams, springs, or riparian habitats.

21 Lone Star Ore Body Development Project EIS Applicable Water Permits Comments requested that the EIS describe the applicable permits and state-adopted, USEPA-approved water quality standards, including beneficial uses, in the project area, and discuss each alternative s compliance with the standards and permits. Other comments regarding the various permits related to water resources included the following permits. CWA Section 404 Permit: Comments stated that the EIS should describe the CWA Section 404 permitting process and the status of the project in that process and provided information that should be included in the site characterization and impact analyses in order to accurately understand the potential impacts of the proposed discharge of fill materials into approximately acres of Waters of the U.S., including identification of the Least Environmentally Damaging Practicable Alternative (see subsections and , below). Comments also stated that the applicant is required to obtain water quality certification from the ADEQ per CWA, Section 401 prior to Section 404 permit issuance. Aquifer Protection Permit: Comments stated that that although the FMSI has amended its individual Aquifer Protection Permit in 2014, the Lone Star project was not addressed in this amendment and the permit may still need to be modified. Comments indicated the EIS should identify the specific requirements of the Arizona s Aquifer Protection Program permit for this project and discuss how the project would meet the groundwater standards included in its permit. Arizona Pollutant Discharge Elimination System (AZPDES) program: Comments stated that stormwater discharges require a permit under AZPDES program and that EIS should discuss the applicability of Arizona s General Permit for Storm Water Discharges Associated with Industrial Activity Mineral Industry (AZMSG ) to this project. Comments indicated that although FMSI has coverage for two existing facilities, they may need to update the Stormwater Pollution Prevention Plan and submit a revised notice of intent if they are expanding or seek separate coverage under the Multi-Sector General Permit for any new site Project Design Elements Relevant to Water Resources As discussed under Section 4.3.1, Proposed Action, comments requested design information to allow the Draft EIS to assess potential impacts to resources. With respect to water resources, comments requested that the Draft EIS disclose how the project would be designed with best available demonstrated control technology for purposes of meeting Arizona groundwater standards included in its Aquifer Protection Program permit. Respondents also requested a description of the procedures that would be used for monitoring the functioning of the waste rock stockpiles and heap leach pads in controlling contact between this material and surface or meteoric water (e.g., maintenance of run on/runoff channels, liners, underdrains, seepage collection areas, growth medium covers; ponding on top of facilities; etc.). Comments indicated the Draft EIS should describe all monitoring locations for surface water, ponded water, and collected seepage; groundwater monitoring wells; and points of compliance on the site. Comments regarding the proposed Project s Reclamation Plan requested that the EIS include a detailed account of closure and post-closure activities associated with the tailings, heap leach pad, waste rock piles, and other facilities, including: Whether a synthetic geomembrane cap will be required to prevent interstitial water infiltrating into heap leach, tailings or waste rock facilities, with details to demonstrate anticipated effectiveness of cover design; How draindown fluids from the tailings and heap leach pads would be captured, treated and controlled over the closure and post-closure period;

Any existing groundwater contamination associated with ongoing activities at the Safford mine. Graphic descriptions and narratives of the acreages and channel lengths, habitat types, values, and functions of waters of the U.S. that may be impacted by the potential discharge of fill materials Impact Analysis Comments stated that the EIS should include the following disclosures related to Water Resources. The potential environmental impacts of the fill and should identify project alternatives designed to avoid or minimize discharge to waters, as well as all possible and required measures to mitigate potential impacts. The potential for groundwater pumping and interception of groundwater by the pit to cause a dewatering cone of depression, as determined through groundwater modeling.

23 Lone Star Ore Body Development Project EIS 4-10 The potential for contamination of meteoric water that contacts existing and proposed waste rock, pit wall rock, heap leach, stockpiles, roads, and other mine facilities. The projected chemical characterization of water in open ponds that would be located at the site, including whether a pit lake or ponding of precipitation might occur in the mine pits. The potential for and effects of movement of any contaminated surface water to the subsurface, including through the pit bottom. Maps of descriptions of the designs of the proposed run-on/run-off channels, seepage collection systems, collection and sedimentation ponds, pump back systems, and any necessary treatment or disposal of these solutions. Discussion of how drainage patterns would change (including post-closure drainage patterns) under each alternative that includes hydrologic and topographic maps of the project area and cumulative impact area. Identify any project components within 25- and 100-year flood plains and disclose potential for runoff to transport sediment or contaminants from disturbed areas at the mine to any surface waters or other potential receptors outside the mine boundaries. Discussion of how accidental releases of hazardous materials would be handled (see Section 4.4.8, Hazardous Materials). Evaluation of each alternative s compliance with the standards and permits. The EIS should discuss how the project would be designed with best available demonstrated control technology for purposes of meeting Arizona groundwater standards included in its Aquifer Protection Program permit. Disclosure by alternative of whether the tailings facility would achieve zero discharge for all phases of the project and, if so, how zero discharge would be achieved. Potential for the Proposed Action or alternatives to affect any existing groundwater contamination plumes and describe any and all measures proposed or implemented to control such contamination. Comments also stated that the cumulative impacts analysis must include analysis of the connected habitats in the Gila River watershed, particularly the Gila River and connected environment downstream and cumulative impacts such as potential pollutant inputs downstream, water diversion upstream, and reduced surface flow into the Gila River Mitigation and Monitoring Comments suggested that mitigation for impacts to surface flows and/or groundwater levels might include riparian habitat enhancement or creation; preservation of habitat along the Gila River, San Pedro River, or Bonita Creek; purchase of water rights to secure flows in the Gila or Bonita Creek; funding of habitat projects at Cluff Ranch and the Willcox Playa (new or reestablished lakes and ponds); and/or a solar water pumping system at Roper Lake to maintain that recreation area's lake levels. The AGFD indicated it would seek compensation for at least two water tanks used by wildlife. Respondents indicated that the EIS should include a comprehensive water quality and quantity monitoring and reporting plan that includes: Procedures for monitoring the functioning of the waste rock stockpiles and heap leach pads in controlling contact between this material and surface or meteoric water (e.g., maintenance of run on/runoff channels, liners, underdrains, seepage collection areas, growth medium covers; ponding on top of facilities; etc.);

24 Lone Star Ore Body Development Project EIS 4-11 A description of all monitoring locations for surface water, ponded water, and collected seepage; groundwater monitoring wells; and points of compliance on the site; and Monitoring frequencies, screening intervals, and parameters to be monitored during all phases of the project, including post-closure. Comments also suggested the EIS should include a storm water pollution prevention plan what discusses specific mitigation measures that may be necessary during operations, closure, and post-closure for each alternative. Respondents recommended that the EIS should include mitigation measures to prevent contamination of water and sediment but did not provide suggestions on the measures that could be incorporate into the water quality plan Vegetation The AGFD, who provided preliminary issues via an Arizona Environmental Online Review Tool Report, identified the Pima Indian Mallow as a Special Status Species documented within five miles of the project area. The report indicated that this species is a species of concern to the USFWS and is classified under the Arizona Native Plant Law (2008) as Salvage Restricted (collection only with permit). Comments requested coordination with the Arizona Department of Agriculture regarding native plants listed on the Arizona Native Plant Law and Antiquities Act. Comments also suggested that revegetation should only be done with only native species indigenous to the area in order to restore the ecosystem to as natural a state as possible after mine closure. Comments indicated that that invasive species may cause alteration to ecological functions or compete with or prey upon native species and can cause social impacts (e.g., livestock forage reduction, or increase wildfire risk). Respondents requested that the EIS evaluate the potential for the introduction of noxious weeds, pathogenic fungi (chytridiomycota), and other organisms which may cause disease or alteration to ecological functions. Comments referenced Arizona s noxious weed regulations (Arizona Revised Statutes, Rules R and R ) and noted that the Arizona Department of Agriculture website contains a list of restricted plants ( Respondents expressed concern about impacts to riparian areas and wetlands. Respondents noted that the GBRNCA is located with two miles of the mine, and indicated that the project area includes part of the Bonita Creek watershed, which contains a riparian ecosystem with plant and animal diversity. Comments also expressed concern about impacts to the xeroriparian areas associated with the Gila River. These comments identified several large washes that traverse the proposed sites of the leach pad (Coyote and Watson Washes and side drainages) and waste rock areas (Bear Springs Canyon) as xeroriparian areas of significant environmental importance (see also Section 4.4.6, Wildlife). Comments stated the EIS should identify both jurisdictional and non-jurisdictional wetland and riparian habitats adjacent to or within the project area, and describe how these waters have already been affected by existing operations, and the extent to which each action alternative might further degrade the quality of these resources. The AGFD recommended early direct coordination with the Project Evaluation Program for projects that could impact any wetlands or riparian habitats. Respondents suggested preparation of the following plans in order to avoid or minimize impacts to vegetation resources. A revegetation plan that identifies: Environmental conditions necessary to re-establish native vegetation outlines species; Density, method of establishment for revegetation, and outlines treatments of invasive of noxious species;

25 Lone Star Ore Body Development Project EIS 4-12 Estimated acreage and areas targeted for reclamation, and description of the intended degree of treatment in each area, including the density, method of establishment for revegetation; Timing of reclamation relative to mining operations, procedures for concurrent reclamation activities, and duration of reclamation treatment; Standards for determining and means of assuring successful reclamation; Means of assuring that all maintenance required for reclaimed areas would continue after operations cease or while operations are suspended; and Prevention and treatment of invasive of noxious species through BMPs such as washing equipment before leaving the site or use of pest and invasive plant control methods recommended by the U.S. department of agriculture (USDA). A short- and long-term monitoring plan with adaptive management guidelines to address needs for replacement vegetation and that monitors revegetation success for at least 5 years. A detailed mitigation plan for jurisdictional and non-jurisdictional wetland and riparian habitat replacement, identifying: Acreage and habitat type that would be created or restored; Resources needed to maintain the mitigation area; Numbers and age of each species to be planted; Maintenance and monitoring plans, including performance standards to determine mitigation success; Size and location of mitigation zones; Parties that would be ultimately responsible for the plan's success; and Contingency plans that would be implemented if the original plan fails. Compensatory mitigation such as riparian habitat enhancement or creation; preservation of habitat along the Gila River, San Pedro River, or Bonita Creek; funding of habitat projects at Cluff Ranch and the Willcox Playa (new or reestablished lakes and ponds), as was included in the ROD for the Dos Pobres mine Wildlife Resources General Concerns Comments expressed concern about the potential impacts to wildlife movement, habitat connectivity, and access to habitat needs. Respondents stated that that development may prevent wildlife from accessing resources, reproducing, re-colonizing areas where local extirpations may have occurred, and ultimately preventing wildlife from fully contributing to ecosystem functions. Comments noted that upland areas support a large diversity of species and stated that streams and washes may provide natural movement corridors for wildlife. Respondents stated the EIS should address the interaction of multiple impacts on wildlife. While individually, each impact may not have a significant effect on any species, analysis of their additive and interactive impacts may reduce the suitability of the area for occupation or use by certain species. The AGFD identified the proposed pit and development rock stockpiles as being located in an area that is important for bighorn sheep habitat connectivity. Comments stated that over 30 bighorn sheep were observed during the 2014 survey in the area and expressed concern that habitat modification may segregate the bighorn population and stop sheep movement between the Gila Mountains and Bonita Creek Canyon.

26 Lone Star Ore Body Development Project EIS 4-13 Comments expressed specific concerns about the impacts of artificial lighting, noise and contact with hazardous and other human-made substances in facility water collection/storage basins, evaporation or settling ponds and/or facility storage yards. Respondents expressed concern about impacts to hunting and game species, noting that the mine historically has provided access for hunting, but that this opportunity has been lost the mine has progressed. Comments expressed concern that groundwater pumping and interception of groundwater by the pit may cause a dewatering cone of depression around the mine and dewater springs, seeps, and similar habitat features important to wildlife. Respondents also expressed concern that hazardous spills, standing water, or pollutants may create a hazard to wildlife including the potential to impact migrating birds or dispersing amphibians such as leopard frogs. Respondents also expressed concern about impacts to aquatic species due to changes in water quality, quantity, chemistry, temperature, and alteration to flow regimes (timing, magnitude, duration, and frequency of floods). Comments included concerns about impacts to the biota of the Gila River through releases of toxins into the river. Comments also identified the Bonita Creek watershed as a riparian ecosystem with plant and animal diversity. Respondents identified the several large washes within the project area (Coyote and Watson Washes and side drainages and Bear Springs Canyon) as potential habitat for numerous species including special status species as well as high value to game species such as desert mule deer and javelina. Comment stated these areas traverse the proposed leach pad and waste rock areas. Comments expressed concern with impacts to avian species including direct mortality, or disturbance of birds nesting, roosting, and utilizing the area. Comments stated that golden eagles are commonly observed in the Gila Mountains in the area of the proposed Lone Star pit and development rock stockpiles. The AGFD noted that Arizona Revised Statutes prohibits the take of birds (and disturbance of nests and eggs) including migratory and non-migratory birds and requested coordination with the USFWS if a take would be a part of this project. Comments noted that exotic invasive wildlife species may include can cause alteration to ecological function. Comments also indicated that the EIS must address the potential for potential for fugitive dust, especially dust that contains toxins, abrasives, or otherwise ecologically disruptive compounds to impact wildlife, especially amphibians and mollusks. Comments specific to reclamation processes asked for additional details regarding commitments by the mining company and agencies regarding operation and maintenance of fencing and wildlife protection measures Affected Environment Comments indicated that the EIS should Identify all petitioned and listed threatened and endangered species and critical habitat, as well as sensitive species, that might occur within the project area. The AGFD provided an Arizona Environmental Online Review Tool Report as part of its scoping submission, and requested that the data contained therein be utilized in the EIS. The report, a preliminary environmental screening tool, identified the following: Special status wildlife species/habitat documented within 5 miles of project vicinity, including federally listed and other special status species (23 species); Wildlife species having of greatest conservation need predicted within project vicinity based on predicted range models (64 species); and Wildlife species of economic and recreation importance predicted within project vicinity (10 species).

27 Lone Star Ore Body Development Project EIS 4-14 Comments specifically requested surveys to determine species with in the project area, and more specifically, to determine if the project area contains noise-sensitive species Impact Analysis Comments suggested that the EIS analysis should: Identify all species or critical habitat that could potentially be directly, indirectly, or cumulatively affected by each alternative; Discuss how surveys were conducted for each species, their findings, and all follow-up surveys and monitoring that would be conducted before, during, and after mining occurs; Include the biological assessment for federally listed species by reference or as an appendix, if one is prepared (to be determined through coordination with the USFWS; and Summarize or include the biological opinion as an appendix in the EIS to demonstrate that the preferred alternative is consistent with the biological opinion. Identify all significant impacts to recreational use, and economic impacts related to wildlife resources and recreation. Comments also stated that the cumulative impacts analysis must include analysis of the connected habitats in the Gila River watershed, particularly the Gila River and connected environment downstream and cumulative impacts such as potential pollutant inputs downstream, water diversion upstream, and reduced surface flow into the Gila River. Respondents stated the analysis must consider cumulative and additive impacts from pollution, habitat fragmentation, transportation and infrastructure, water diversion, groundwater pumping, and other disturbance Mitigation and Monitoring Comments indicated that the EIS should discuss the mitigation measures that would be taken to minimize impacts to special status species; address any dewatering or other water-related impacts to wildlife; and prevent exposure of migratory waterfowl and other wildlife to any mine-influenced waters or other hazards associated with the proposed operation. Respondents provided the following suggestions to avoid or minimize wildlife impacts. Project Design Maintain streams and washes in their natural state and retain upland areas to facilitate wildlife movement. Design slopes to discourage wading birds and/or use fencing, netting, hazing or other measures to exclude wildlife from in water collection/storage basins, evaporation, settling ponds and/or facility storage yards. Incorporate exclusionary fencing and netting for leach pads to prevent ongoing take of terrestrial and avian wildlife. Consider species and purpose in fencing design; see AGFD Fencing Guidelines located at General project area fencing specifications should generally include barbless wire on the top and bottom, with a maximum fence height of 42 inches, and a minimum bottom height of 16 inches, but may depend on big game present within project area. Limit lighting to minimum amount needed for safety. Use narrow spectrum bulbs as often as possible to lower the range of species affected by lighting. Shield or otherwise direct lighting so that light reaches only areas needing illumination. Improve irrigation design to decrease water use.

28 Lone Star Ore Body Development Project EIS 4-15 Coordinate with AGFD Bat Coordinator when developing alternatives to mine closures. Timing Stipulations Conduct dredging (if applicable) outside of spawning seasons for fish and other aquatic species. Conduct project activities outside of breeding seasons to minimize impacts to noise-sensitive species. Measures to minimize spread of noxious or invasive wildlife species as identified by USDA and per AGFD regulations regarding the importation, purchasing, and transportation of wildlife and fish. Pre- and post-project survey/monitoring to determine alternative access/exits to mines and to identify and/or minimize potential impacts to bat species. Development of an avian conservation plan. Comments also suggested that compensatory mitigation should be identified for any residual impacts to wildlife resources and habitat. Suggested included: For bighorn sheep: the construction of bighorn sheep crossings on the haul road to and from the Lone Star area and on the surrounding development rock stockpiles, forming waste rock piles in a way that maintains a corridor through the area, funding capture/relocation efforts to expand bighorn sheep populations, research, monitoring, or other mitigations. Such mitigation might include grassland restoration within the area, habitat improvements through prescribed fire, or direct purchase of property currently unavailable but necessary to improve management capability. For mule deer, javelina and quail: grassland restoration within the area, habitat improvements through prescribed fire, or direct purchase of property currently unavailable but necessary to improve management capability. For impacts to surface flowers and groundwater levels that would impact wildlife: preservation of habitat along the Gila River, San Pedro River, or Bonita Creek; funding of habitat projects at Cluff Ranch and the Willcox Playa. For loss of wildlife tank: two new mule deer/javelina wildlife waters in areas where needed. Comments also noted that the EIS should discuss the effectiveness of mitigation measures to protect wildlife, indicate how they would be implemented and enforced, and describe the maintenance and monitoring requirements necessary to ensure their effectiveness. The AGFD also indicated that they would like to discuss with the Corps how to incorporate costs in planning for conservation purposes into the cost of the project. The AGFD also stated that it is the policy of the Arizona Game and Fish Commission that the AGFD seek compensation at a 100% level (i.e. no net loss), when feasible, for actual or potential habitat losses resulting from land and water projects Cultural Resources Comments noted that while the project is anticipated to adversely impact cultural resources that are eligible for listing on the National Register of Historic Places, the scoping notice did not contain information regarding the type of resources that will be impacted. Respondents indicated that there are Tribal Lands within the vicinity of the project area and suggested coordination with the San Carlos Apache Tribal Council. Comments also noted that the proposed project area is within the ancestral lands of the Four Southern Tribes (Gila River Indian Community; Salt River Pima-Maricopa Indian Community; Ak-Chin Indian Community and the Tohono O'Odham Nation).

29 Lone Star Ore Body Development Project EIS 4-16 Comments recommended that tribal consultation take place early in the scoping phase of the project to ensure that all issues are adequately addressed in the EIS, and indicated that efforts should be made to avoid or mitigate impacts to culturally significant sites. The White Mountain Apache THPO requested the Cultural Survey report conducted for the project. The Gila River Indian Community THPO indicated they would participate as a consulting tribe for this undertaking. The White Mountain Apache THPO requested the Cultural Survey report conducted for the project. The San Carlos Apache Tribe indicated requested the Cultural Survey report conducted for the project and requested that the Corps contact them to clarify potential impacts to cultural and water resources Hazardous Materials Comments expressed concern about potential impacts to wildlife from hazardous materials (see Sections 4.4.6) and provided design specification to help reduce contact with these materials). Respondents indicated that the EIS should discuss how accidental releases of hazardous materials would be handled, and identify the potential impacts of failure of the solution containment systems, methods for discovering such failures, and the degree to which impacts would be reversible. Comments also stated that the EIS should include details regarding the mine s petroleum-contaminated soil management plan Recreation The AGFD Environmental Review Report identified ten wildlife species projected to occur within the project vicinity as having economic and recreation importance. Comments expressed concern about impacts to hunting and game species, noting that the mine historically has provided access for hunting, but that this opportunity has been lost the mine has progressed Socioeconomics, including Environmental Justice Comments contained a concern about the boom and bust effect on the community after non-local workers leave the area. Comments included a summary from the Town of Clifton Police regarding a public nuisance violation detail conducted in February The summary noted that the detail was organized due to ongoing complaints from citizen and business owner regarding people sleeping in vehicles; inappropriate usage of public parks; and other areas; and garbage, human waste and other waste materials being disposed of improperly. The detail focused on three areas of concern (Clifton Recreational Vehicle Park, a dirt lot at the intersection of Skyline Road and Highway 191, and a public parking lot across from the Sacred Heart Church on Chase Creek Road. The detail resulting in 14 documented violations in the Town of Clifton. All but one violator provided information regarding employment. The submission suggested that all employees associated with the project should comprise locals, i.e., those with a permanent residence. Respondents noted that EO on Environmental Justice requires analysis of disproportionate adverse impacts of federal actions on minority and low-income populations and indicated that the EIS document opportunities for affected communities to provide input into the NEPA process; identify minority and low-income populations potentially affected by the project; address whether any of the alternatives would cause any disproportionate adverse impact (such as displacement, changes in existing resources or access, or community disruption); explore potential mitigation measures for any adverse environmental justice effects; and state whether the analysis meets the Corps environmental justice requirements. The AGFD Environmental Review Report identified 10 wildlife species of economic and recreation importance predicted within the project vicinity. The list included quail, pigeon and dove species, big game (mule deer, bighorn sheep, bear, and mountain lion) as well as javelina and squirrel. Comments expressed concern about the loss of hunting access (also see Section 4.4.9, Recreation).

30 Lone Star Ore Body Development Project EIS 4-17 Comments cited positive social and economic contributions of mining companies such as FMSI to the overall condition of Greenlee and Graham counties, local communities, and individuals living therein, both in terms of employment opportunities as well as specific infrastructure projects that have benefitted communities in the area Special Designations Comments indicated the GBRNCA, designated under the authority of the Arizona Desert Wilderness Act of 1990 (Public Law ), is within two miles of the project area boundary and expressed concern about impacts to the GBRNCA Visual Resources Submissions expressed concern about visual impacts to the GBRNCA and other nearby areas as a result of landform alterations. Comments indicated that a view of a flat plateau in between two mountains would not mitigate the impacts from mining to the maximum degree possible. Submittals also expressed concern about mine lighting, particularly as it related to wildlife. Comments recommended that the project utilize the contouring proposed at the Rosemont mine, as a better way to ensure that discarded rock fits into the surrounding environment and reduce visual impacts. Comments suggested minimizing lights to the degree only needed for human safety, using narrow spectrum bulbs as often as possible, and shielding or otherwise directing lighting so that light reaches only areas needing illumination Cumulative Impacts Comments provided links to cumulative impact analysis guidance provided by the CEQ and USEPA; stated that the EIS should describe the potential cumulative impacts associated with the proposed project and alternatives in light of other past, present, and reasonably foreseeable future actions (as the methodology used to assess those impacts); and identified the adjacent and active Dos Pobres and San Juan operations as actions that should be considered in this analysis. Comments suggested the following element to be included in the cumulative impacts analysis. A description of the cumulative effects study areas for each resource that could be affected by the proposed project, focusing on natural boundaries, resources of concern, and identifying which resources are analyzed, which ones are not, and why. Identify all other on-going, planned, and reasonably foreseeable projects in the study area, including not only existing operations but also other mining projects and non-mining activities in the project area, using existing studies as available for quantifying cumulative impacts. Include appropriate baselines for the resources of concern with an explanation as to why those baselines were selected. Identify mitigation as needed, stating who would be responsible and how mitigation implementation would be ensured Reclamation Comments listed details regarding reclamation processes that respondents felt should be included in FMSI s Reclamation Plan in order to accurately assess project impacts. These are discussed in Section 4.3.1, Proposed Action; Section 4.4.2, Geology; Section 4.4.3, Soils; Section Vegetation; and Section 4.4.6, Wildlife.

31 Lone Star Ore Body Development Project EIS 4-18 Comments expressed concern about the potential for success of reclamation and stated that the Corps must include restoration of mine tails, dumps, and pit to preconstruction conditions after closure of the mine where feasible and environmentally advisable. Comments also stated that the EIS should include reclamation bonding requirements and amounts for the proposed project and alternatives; how the bond could be modified during the course of operations if temporary, long term, or perpetual treatment and/or remediation needs are discovered during operations; as well as any other measures regulators have in place to ensure funds would be immediately available should the mine operator or its insurer be unable to fund the required reclamation or closure activities Mitigation and Monitoring Comments indicated that the Draft EIS must thoroughly identify and describe appropriate mitigation measures associated with the project, specifying which ones would be committed to by the mine operator (i.e., design features) and those required by the Corps or other federal, state, or local agencies. Comments stated that discussions of mitigation should include the following: How each measure would mitigate the impact, Anticipated effectiveness of the measure, The means of implementing each mitigation measure, Who would be responsible for implementing the measure, and Whether the measure is enforceable. Comments stated that the EIS should include a mitigation and monitoring plan that include: Implementation monitoring and effectiveness monitoring; Contingency measures that would be implemented if initial mitigation measures are unsuccessful; The agency responsible for enforcement and oversight should the mine operator fail to properly follow the long-term post-closure plan; The time frame over which long term management activities would occur or if they might be necessary into perpetuity. If long-term post-closure monitoring and management would be needed, the plan should include a general description of the funding mechanism, including: Timing of payments into the trust fund, How to ensure the trust fund would be bankruptcy remote, Acceptable financial instruments, Tax status of the trust fund, Trust fund beneficiaries, and Operator with responsibility/liability for financial assurance at this site. Comments stated that the inclusion of such information into the mitigation and monitoring plan of this mitigation plan would be essential in determining if impacts are mitigated over the long term and would be the difference between a project sufficiently managed over the long-term by the site operator, or an unfunded/under-funded contaminated site that becomes a liability for the Federal government.

32 Lone Star Ore Body Development Project EIS Non-substantive Comment Summary Statements of Support of the Project Some comments from individuals expressed support for the project and/or commended FMSI for its reclamation record or contributions to the community Statements of Opposition to the Project Several comments from individuals and tribes expressed a general opposition to mining, the discharge of fill into Waters of the U.S., or the expansion of existing mining site.

33 Lone Star Ore Body Development Project EIS Issue Summary Based on these external scoping efforts, the Corps has identified a number of issues for the proposed Lone Star Ore Body Development Project EIS. 5.1 Process Scoping comments identified a need for multiple consultation and coordination processes, including: Biological consultations and coordination (USFWS, AGFD); Cultural resources consultations (State Historic Preservation Office); Consultation with tribes (including Ak-Chin Indian Community, Gila River Indian Community, Salt River Pima-Maricopa Indian Community, San Carlos Apache Tribe, Tohono O'Odham Nation, and the White Mountain Apache Tribe); and Coordination with other agencies from which permits are required, such as ADEQ. The Corps has been in contact with these federal, state, and local agencies and tribes for comments and concerns. The comments contained in Section 4.0, Comment Summaries, include preliminary comments from responding interested agencies and tribal entities, and the issues below reflect their concerns and interests. The Corps will continue to be in contact with applicable federal, state, and local agencies and tribes throughout the NEPA process. 5.2 Purpose and Need Comments stated that the EIS needs to adequately identify and describe the underlying need(s) for the project and the associated objectives or outcomes for purposes of both the NEPA analysis and the CWA Section 404(b)(1) alternatives analysis. 5.3 Proposed Action and Alternatives Proposed Action Comments stated that the Proposed Action description needs to adequately identify all resource requirements and include clear description of the processes and best available demonstrated control technology that would be used during the life of the project. Respondents also requested that the EIS include a petroleum-contaminated soil management plan, hazardous material storage plans and comprehensive reclamation plan for review and incorporation into the analysis Range of Alternatives As part of the EIS process and in accordance with the USEPA s 404(b)(1) guidelines, the Corps will conduct a comprehensive alternative assessment. Social and environmental issues, concerns, and opportunities will be considered in this assessment. The Corps will develop a range of reasonable alternatives to be considered in detail in the Draft EIS. In reviewing possible project alternatives for consideration in the EIS, the Corps will examine numerous locations, operational methods, and mitigation measures. The type and range of alternatives will be determined from public comments and key issues that have been identified during the scoping process, as well as reviewing the purpose of and need for the proposed tailings storage facility. Some alternatives may be eliminated from detailed evaluation because they do not meet the purpose and need of the project, because they are outside the bounds of this project, or they have technical complications that would prohibit implementation. In addition, alternatives may be eliminated because they do not meet practicability requirements as described in the USEPA s 404(b)(1) guidelines (40 CFR Part 230).

34 Lone Star Ore Body Development Project EIS 5-2 NEPA requires that a no action alternative be considered in EIS documents. Under the no-action alternative, the 404 permit for the proposed tailings storage facility would be denied. This alternative serves as the baseline for estimating the effects of action alternatives. The baseline for analysis would be the existing condition of the environment. 5.4 Resource Issues The actual analysis of the Proposed Action and alternatives will be included in the Draft EIS and will include a discussion of environmental protection measures, mitigation requirements, and operational constraints. The Draft EIS also will identify the least environmentally damaging practicable alternative. Based on the comments submitted during external scoping and summarized above, the Corps has identified the following significant issues to be analyzed in depth in the EIS Air Resources, including Climate Change Identify project-related air quality impacts. Areas of concern include: 1) impact to NAAQS; 2) impact to impacts to Class I PSD areas, including visibility impacts; 3) releases of HAPs to air, soil, and water resources; 4) impacts of the project on climate change; and 5) consideration of mitigation measures to reduce air pollutant emissions and GHGs Geology and Geochemistry Evaluate the area s geochemistry.

38 Lone Star Ore Body Development Project EIS Appendix A Federal Register Notice of Intent

39 212 Federal Register I Vol. 80, No. 2 I Monday, January 5, 2015 I Notices DEPARTMENT OF DEFENSE Department of the Army, Corps of Engineers Notice of Intent To Prepare a Draft Environment Impact Statement for the Proposed Lone Star Ore Body Development Project in Graham County, Arizona AGENCY: U.S. Army Corps of Engineers, DoD. ACTION: Notice of Intent. SUMMARY: The U.S. Army Corps of Engineers, Los Angeles District (Corps) is examining the environmental consequences associated with Freeport McMoRan Safford Inc.'s (FMSI) application for a Department of the Army permit under section 404 of the Clean Water Act for the proposed development of the mineral resources associated with the Lone Star ore body for the purpose of producing copper (the Lone Star Project). The proposed development would include the construction of mining facilities, including an open pit mine and attendant development rock stockpiles and heap leach facilities, which will allow continued mining at the Safford Mine Facility using conventional openpit mining, heap leaching techniques, and solution extraction/electrowinning (SX/EW) processing, and utilizing as much of the existing Safford Mine Facility infrastructure and processing facilities as practicable. The construction of the proposed facilities would discharge fill materials into approximately acres of waters of the United States (U.S.). The primary federal environmental concerns are the proposed discharges of fill material into waters of the U.S. and the potential for significant adverse environmental effects resulting from such activities. Therefore, to address these concerns in accordance with the National Environmental Policy Act (NEP A), the Corps is requiring preparation of an Environmental Impact Statement (EIS) prior to consideration of any permit action. The action must comply with the section 404(b)(1) Guidelines (40 CFR part 230) and not be contrary to the public interest to be granted a Corps permit. The Corps may ultimately make a determination to permit or deny the above project, or permit or deny modified versions of the above project. FOR FURTHER INFORMATION CONTACT: Questions about the proposed action or the scoping of the Draft EIS can be answered by Michael Langley, Corps Senior Project Manager, at (602) Comments regarding scoping of the Draft EIS shall be addressed to: U.S. Army Corps of Engineers, Los Angeles District, Arizona Regulatory Branch, ATTN: SPL MWL, 3636 North Central Avenue, Suite 900, Phoenix, Arizona , or michael. w.langley@usace.army.mil. Comment letters sent via electronic mail shall include the commenter's physical address and the project title "Lone Star Ore Body Development Project" shall be included in the subject line. SUPPLEMENTARY INFORMATION: 1. Project Site and Background Information: The Lone Star copper ore body proposed for development is located within the boundary of the existing FMSI Safford Mine Facility, north of the City of Safford, Graham County, Arizona. FMSI owns and manages approximately 36,050 acres of privately held lands within and surrounding the Safford Mine Facility, which has been in operation for almost 7 years. The Safford Mine Facility is located within the Safford Mining District, and lands within the district have been used for mining activities by various entities for more than a century. FMSI (formerly Phelps Dodge Safford Inc.) first began development of an underground copper mining operation in the district in the 1960s, and later purchased other copper mining operations in the vicinity. Between 1994 and 1996, FMSI initiated discussions to obtain authorization from the Bureau of Land Management (BLM) and the Corps to develop open pit copper mining operations in the district, and in May 1996, formally initiated NEPA review of these proposals through submission of a Mine Plan of Operations (MPO) to the BLM. NEP A review of the project, termed the Dos Pobres/San Juan Project (DP/SJ Project) after the ore bodies proposed for development, involved the publication of a Draft Environmental Impact Statement (DEIS) in September 1998, a Final Environmental Impact Statement (FEIS) in December 2003, and a BLM Record of Decision (ROD; No [AZ-040] AZA-31133) in June As a component of the NEP A review, the Corps completed a section 404(b)(1) Alternatives Analysis in October 1997 and issued a section 404 Individual Permit (No MB) for impacts to waters of the U.S. from development of the DP/SJ Project on September 27, The Safford Mine Facility is currently an open-pit copper mining operation consisting of two pits: The Dos Pobres Pit and the San Juan Pit. The handling, processing, and support infrastructure for mineral resources recovered from the two pits is integrated into a single system consisting of a three-stage crushing system, two drum agglomerators, a single heap leach pad, SX/EW processing facility, and support facilities. Each of the pits has an associated development rock stockpile: For Dos Pobres immediately west of the pit, and for San Juan immediately south of the pit. A clay borrow pit is located in the southeastern portion of the Safford Mine Facility. 2. Proposed Action: FMSI has proposed the development of the mineral resources associated with the Lone Star ore body, located on FMSI's privately owned lands and proximate to the existing Safford Mine Facility. Development of the Lone Star copper ore body (the Lone Star Project) was considered as a Reasonably Foreseeable Future Action (RFFA) and was included in the NEPA review of cumulative impacts for the 2003 FEIS. The applicant has designed the proposed Lone Star Project to make use of as much of the existing Safford Mine Facility infrastructure as is practicable. Although the location of the open pit for the Lone Star Project is tied to the physical location of the mineral resource, the locations of the remaining project elements have been optimized to continue using existing infrastructure wherever possible. New elements anticipated as necessary for the development of the Lone Star Project include the open pit, a heap leach stockpile and associated solution management systems, development rock stockpiles, the ore haulage/conveyance route between the pit and crusher, additional power distribution infrastructure, an expanded clay borrow source, and additional stormwater management facilities. The Lone Star Project proposes discharges to waters of the U.S. for the development and operation of the heap leach stockpile, the development rock stockpiles, the haul road, and for the expansion of the clay borrow pit. Continued use of the existing facilities including the existing crushing facilities, SX/EW facilities, the majority of the existing support infrastructure for the current leach pad, and the mine access road are not anticipated to require the discharge of fill to waters of the U.S. Construction and operation of the remaining Lone Star Project elements including the open pit and power distribution infrastructure are not anticipated to require the discharge of additional fill to waters of the U.S. 3. Issues: There are several potential environmental issues that will be addressed in the Draft EIS. Additional issues may be identified during the

40 January 5, 2015/ Notices 213 scoping process. Issues initially identified for evaluation in the Draft EIS include: a. Visual/aesthetics impacts from landform alterations, b. air quality impacts from construction and operation of the facility, c. cultural resources (prehistoric and historic resources), d. surface water hydrology and quality, e. groundwater hydrology and quality, f. potential land use incompatibility, g. noise impacts from construction and operation, h. socioeconomic effects, i. soils and geology resources, j. transportation network impacts, k. environmental justice l. biological impacts m. impacts to waters of the U.S., and n. cumulative impacts. 4. Alternatives: Alternatives to the proposed action are being developed for evaluation in the EIS. The Draft EIS will include a co-equal level of analysis of the No-Action and project alternatives considered. Alternatives will be further formulated and developed during the scoping process. 5. Scoping: The Corps will conduct a public scoping meeting in an open house format for the proposed Lone Star Ore Body Development Project Draft EIS to receive public comment and to assess public concerns regarding the appropriate scope and preparation of the Draft EIS. Participation in the public meeting by federal, state, local, and tribal agencies and other interested organizations is encouraged. The meeting will be held on February 4, 2015, 6:00p.m. to 9:00p.m. (Arizona Time Zone) at the Manor House Convention Center, 415 E. U.S. Highway 70, Safford, Arizona Representatives from the Corps and Freeport-McMoRan Safford Inc. will provide a presentation for attendees at 7:00 p.m. Comments on the proposed action, alternatives, or any additional concerns should be submitted in writing. Written and electronic comment letters will be accepted through February 20, The Corps also anticipates formally consulting with the U.S. Fish and Wildlife Service under section 7 of the Endangered Species Act and with the State Historic Preservation Officer and appropriate Tribal Historic Preservation Officers under section 106 of the National Historic Preservation Act. 6. Availability of the Draft EIS: The Draft EIS is expected to be published and circulated in the fourth quarter of 2015, and a public meeting will be held after its publication.

Description ofrequest: Trinity Conservancy, Inc. (license) requests amendment of the Trinity Project's resident fish habitat and project tailrace plan and effectiveness monitoring plan, which was approved in a Commission order issued April 22, The Trinity Project uses water from Phelps Creek, then returns it via the project tailrace to the Chiwawa River, several hundred yards above where the historic natural channel of Phelps Creek meets the Chiwawa River. The April 22, 2008 order approved two alternatives for the tailrace plan, both involving routing of water through a short section of pipe to a new 858-foot open tailrace channel that would follow natural contours to a confluence with Phelps Creek above where it meets the Chiwawa River. The licensee now requests, based on consultation with resource agencies, an amendment of the tailrace plan which would utilize 680 feet of primarily buried pipe for the first section of the new tailrace, leading to a shorter open reach. The change would reduce water loss and provide enhanced salmonid habitat in the area where the tailrace would join Phelps Creek. The licensee also requests approval of minor modifications to the effectiveness monitoring plan. l.

43 to review today s public notice and provide views on the proposed work. By providing substantive, site-specific comments to the Corps Regulatory Division, you provide information that support the Corps decision-making process. All comments received during the comment period become part of the record and will be considered in the decision. This permit will be issued, issued with special conditions, or denied under Section 404 of the Clean Water Act. Written comments should be mailed to: U.S. Army Corps of Engineers, Los Angeles District Arizona Regulatory Branch ATTN: SPL MWL 3636 N. Central Ave, Suite 900 Phoenix, AZ Alternatively, comments can be sent electronically to: Michael.W.Langley@usace.army.mil. The mission of the U.S. Army Corps of Engineers Regulatory Program is to protect the Nation's aquatic resources, while allowing reasonable development through fair, flexible and balanced permit decisions. The Corps evaluates permit applications for essentially all construction activities that occur in the Nation's waters, including wetlands. The Regulatory Program in the Los Angeles District is executed to protect aquatic resources by developing and implementing short- and long-term initiatives to improve regulatory products, processes, program transparency, and customer feedback considering current staffing levels and historical funding trends. Corps permits are necessary for any work, including construction and dredging, in the Nation's navigable water and their tributary waters. The Corps balances the reasonably foreseeable benefits and detriments of proposed projects, and makes permit decisions that recognize the essential values of the Nation's aquatic ecosystems to the general public, as well as the property rights of private citizens who want to use their land. The Corps strives to make its permit decisions in a timely manner that minimizes impacts to the regulated public. During the permit process, the Corps considers the views of other Federal, state and local agencies, interest groups, and the general public. The results of this careful public interest review are fair and equitable decisions that allow reasonable use of private property, infrastructure development, and growth of the economy, while offsetting the authorized impacts to the waters of the United States. The permit review process serves to first avoid and then minimize adverse effects of projects on aquatic resources to the maximum practicable extent. Any remaining unavoidable adverse impacts to the aquatic environment are offset by compensatory mitigation requirements, which may include restoration, enhancement, establishment, and/or preservation of aquatic ecosystem system functions and services. Evaluation Factors The decision whether to issue a permit will be based on an evaluation of the probable impact including cumulative impacts of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefit, which reasonably may be expected to accrue from the proposal, must be balanced against its reasonably foreseeable detriments. All factors which may be relevant to the proposal will be considered including the cumulative effects thereof. Factors that will be considered include conservation, economics, 2

44 aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards, flood plain values, land use, recreation, water supply and conservation, water quality, energy needs, safety, food production and, in general, the needs and welfare of the people. In addition, if the proposal would discharge dredged or fill material, the evaluation of the activity will include application of the EPA Guidelines (40 CFR Part 230) as required by Section 404 (b)(1) of the Clean Water Act. The Corps of Engineers is soliciting comments from the public; Federal, state, and local agencies and officials; Indian tribes; and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects, and the other public interest factors listed above. In this case, comments are used in the preparation of an Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act. Comments are also used to determine the overall public interest of the proposed activity. Preliminary Review of Selected Factors EIS Determination- A determination has been made that an EIS is required for the proposed activities, based on the Corps s independent determination that the proposed action could potentially result in significant impacts. The Draft EIS is expected to be published in late Water Quality- The applicant is required to obtain water quality certification, under Section 401 of the Clean Water Act, from the Arizona Department of Environmental Quality. Section 401 requires that any applicant for an individual Section 404 permit provide proof of water quality certification to the Corps of Engineers prior to permit issuance. Cultural Resources- Based on information collected thus far, the project will adversely impact cultural resources that are eligible for listing on the National Register of Historic Places. Consultation with Native American Tribes and the State Historic Preservation officer will occur with respect to cultural resources impacts associated with this project. Native American Tribes will also be consulted regarding the presence of any traditional cultural properties that could potentially be affected by this project. Endangered Species- Preliminary determinations indicate that the proposed activity would potentially affect federally-listed endangered or threatened species, or their critical habitat. Therefore, formal consultation under Section 7 of the Endangered Species Act is required at this time. Public Hearing- The Corps is conducting a public scoping meeting to solicit input from the public about the proposed project and the preparation of the EIS. This meeting will be held on Wednesday evening, February 4, 2015 at the Manor House Convention Center, 415 E. U.S. Highway 70, Safford, Arizona, from 6:00 to 9:00 PM (Arizona time). A presentation will be given by representatives from the Corps and Freeport-McMoRan Safford Inc. starting at 7:00 PM (Arizona time). The meetings will consist of an open house and presentation. During approximately the first hour of the meeting, attendees will have the opportunity to view displays provided by the Corps and the applicant that provide information on various aspects of the project, environmental resources in the project area, and the Clean Water Act Permitting and NEPA processes. Technical experts will be available at these displays to answer questions about the project. After this initial open house period, a presentation will be provided by the Corps Project Manager and a representative from Asarco. This Page 3 of 10

45 presentation will provide background information about the proposed project and information about the Corps permitting and EIS processes. Information will also be provided regarding various ways to provide input to the project manager for inclusion in the administrative record. After the presentation concludes, the open house will continue until the meeting ends. Attendees who wish to comment on this project can do so during the meeting by providing written comments that can be left with Corps staff or submitted at a later date. There will be no provisions made for public oral comments during the course of these meetings. The Corps will be receiving scoping comments until the close of the comment period on February 20, Proposed Activity for Which a Permit is Required Basic Project Purpose- The basic project purpose comprises the fundamental, essential, or irreducible purpose of the proposed project, and is used by the Corps to determine whether the applicant's project is water dependent (i.e., requires access or proximity to or siting within the special aquatic site to fulfill its basic purpose). Establishment of the basic project purpose is necessary only when the proposed activity would discharge dredged or fill material into a special aquatic site (e.g., wetlands, pool and riffle complex, mudflats, coral reefs). Because no special aquatic sites would be impacted, identification of the basic project purpose is not necessary. The project is not water dependent. Overall Project Purpose- The overall project purpose serves as the basis for the Corps' 404(b)(1) alternatives analysis and is determined by further defining the basic project purpose in a manner that more specifically describes the applicant's goals for the project, and which allows a reasonable range of alternatives to be analyzed. The overall project purpose for the proposed project is the construction of mining facilities, including an open pit mine and attendant development rock stockpiles and heap leach facilities, which will allow continued mining at the Safford Mine Facility through the development of the mineral resources associated with the Lone Star ore body using conventional open-pit mining, heap leaching techniques, and solution extraction/electrowinning (SX/EW) processing, and utilizing as much of the existing Safford Mine Facility infrastructure and processing facilities as practicable, for the purpose of producing copper. Additional Project Information Background Located in eastern Arizona, the Safford Mine Facility has been in operation for almost 7 years under the ownership of the applicant, formerly Phelps Dodge Safford Inc. The applicant owns and manages approximately 36,050 acres of privately held lands within and surrounding the existing Safford Mine Facility, north of the City of Safford, Graham County, Arizona. The Safford Mine Facility is located within the Safford Mining District, and lands within the district have been used for mining activities by various entities for more than a century. The applicant (or its predecessors) first began development of an underground copper mining operation in the district in the 1960s, and later purchased other copper mining operations in the vicinity. Between 1994 and 1996, the applicant initiated discussions to obtain authorization from the Bureau of Land Management (BLM) and the Corps to develop open pit copper mining operations in the district, and in May 1996, formally initiated National Environmental Policy Act (NEPA) review of these proposals through submission of a Mine Plan of Operations (MPO) to the BLM. NEPA review of the project, termed the Dos Pobres/San Juan Project (DP/SJ Project) after the ore bodies proposed for development, involved the publication of a Draft Environmental Impact Statement (DEIS) in Page 4 of 10

46 September 1998, a Final Environmental Impact Statement (FEIS) in December 2003, and a BLM Record of Decision (ROD; No [AZ-040] AZA-31133) in June As a component of the NEPA review, the Corps completed a Section 404(b)(1) Alternatives Analysis in October 1997 and issued a Section 404 Individual Permit (No MB) for impacts to waters of the U.S. from development of the DP/SJ Project on September 27, The Safford Mine Facility is currently an open-pit copper mining operation consisting of two pits: the Dos Pobres Pit and the San Juan Pit. The handling, processing, and support infrastructure for mineral resources recovered from the two pits is integrated into a single system consisting of a threestage crushing system, two drum agglomerators, a single heap leach pad, SX/EW processing facility, and support facilities. Each of the pits has an associated development rock stockpile: for Dos Pobres immediately west of the pit, and for San Juan immediately south of the pit. A clay borrow pit is located in the southeastern portion of the Safford Mine Facility. Project Description The applicant has proposed the development of the mineral resources associated with the Lone Star ore body, located on the applicant s privately owned lands and proximate to the existing Safford Mine Facility. Development of the Lone Star copper ore body (the Lone Star Project) was considered as a Reasonably Foreseeable Future Action (RFFA) and was included in the NEPA review of cumulative impacts for the 2003 FEIS. The applicant has designed the proposed Lone Star Project to make use of as much of the existing Safford Mine Facility infrastructure as is practicable. Although the location of the open pit for the Lone Star Project is tied to the physical location of the mineral resource, the locations of the remaining project elements have been optimized to continue using existing infrastructure wherever possible. New elements anticipated as necessary for the development of the Lone Star Project include the open pit, a heap leach stockpile and associated solution management systems, development rock stockpiles, the ore haulage/conveyance route between the pit and crusher, additional power distribution infrastructure, an expanded compactible soil borrow source, and additional stormwater management facilities. The Lone Star Project proposes discharges to waters of the U.S. for the development and operation of the heap leach stockpile, the development rock stockpiles, the haul road, and for the expansion of the clay borrow pit. Continued use of the existing facilities including the existing crushing facilities, SX/EW facilities, the majority of the existing support infrastructure for the current leach pad, and the mine access road are not anticipated to require the discharge of fill to waters of the U.S. Construction and operation of the remaining Lone Star Project elements including the open pit and power distribution infrastructure are not anticipated to require the discharge of additional fill to waters of the U.S. Issues There are a number of potential issues that will be addressed in the Draft EIS. Additional issues may be identified during the scoping process. Issues initially identified for evaluation in the EIS as potentially significant include: Aesthetics and Visual Resources Air Quality Cultural and Historic Resources Surface Water Hydrology and Watershed Resources Groundwater Hydrology Land Use/Planning Blasting Noise and Vibration Socioeconomics Soils and Geology Resources Transportation Page 5 of 10

47 Environmental Justice Biological Resources Cumulative Impacts Alternatives Several alternatives are being considered for the proposed action. The Draft EIS will include a co-equal level of analysis of the No Action Alternative and the project alternatives considered. Alternatives are currently being developed to address the alternatives evaluation requirements under both the 404(b)(1) alternatives analysis guidelines required for evaluation of the Section 404 permit and the NEPA process. These alternatives will be further formulated and developed during the scoping process and assessed in the Draft EIS. Proposed Mitigation The proposed mitigation may change as a result of comments received in response to this public notice, the applicant's response to those comments, and/or the need for the project to comply with the 404(b)(1) Guidelines. In consideration of the above, the proposed mitigation sequence (avoidance/minimization/compensation), as applied to the proposed project is summarized below: Avoidance/Minimization According to the applicant, the project was designed to avoid impacts to waters of the U.S. to the extent practicable. The continued use of existing operational infrastructure wherever possible was considered a general criterion of this minimization. Proposed elements of the Project include the continued use of the existing facilities including the existing crushing facilities, SX/EW facilities, the majority of the existing support infrastructure for the current leach pad, and the mine access road. Compensation The applicant proposes compensatory mitigation for unavoidable impacts to waters of the U.S. through permittee-responsible habitat restoration, contribution to an in-lieu fee program, or a combination thereof. Proposed Special Conditions Special Conditions have not yet been developed and will be based on the results of the EIS and 404 permit analysis. For additional information please call Michael Langley of my staff at or via at Michael.W.Langley@usace.army.mil. This public notice is issued by the Chief, Regulatory Division. Regulatory Program Goals: To provide strong protection of the nation's aquatic environment, including wetlands. To ensure the Corps provides the regulated public with fair and reasonable decisions. To enhance the efficiency of the Corps administration of its regulatory program. U.S. ARMY CORPS OF ENGINEERS LOS ANGELES DISTRICT 3636 N. Central Ave, Suite 900 Phoenix, AZ Page 6 of 10

64 Water Resources Lone Star Ore Body Development Project Environmental Impact Statement Groundwater The Lower Basin Fill Aquifer, the Project s proposed water source, is isolated from the alluvial aquifers used for local community water supplies by a confining clay unit. Surface Water Project proposes discharge of fill to waters of the U.S. for construction/operation of the heap leach pad, waste rock stockpiles, haul road, and clay borrow pit. FMSI proposed avoidance and minimization measures in its Project design, and compensatory mitigation for unavoidable impacts through habitat restoration or contribution to a fee program. The EIS will disclose how the Project would affect groundwater and surface water quality and quantity and identify appropriate mitigation measures to be incorporated to minimize adverse impacts to water resources, if necessary.

65 Biological Resources Lone Star Ore Body Development Project Environmental Impact Statement The EIS will analyze how wildlife resources, threatened and endangered species, sensitive species, and habitat would be affected. Section 7 of the Endangered Species Act directs federal agencies to ensure authorized actions are not likely to jeopardize the continued existence of threatened or endangered species or result in destruction Are there other issues regarding wildlife or threatened and endangered species that should be considered during alternatives development or impact analysis? of critical habitat. A biological assessment will be prepared to examine impacts to federally listed species (anticipated to include southwestern willow flycatcher and yellow-billed cuckoo). Do you have proposed mitigation measures that may help minimize adverse impacts to species or habitat?

66 Cultural Resources Lone Star Ore Body Development Project Environmental Impact Statement The EIS will analyze how recorded archaeological resources would be affected and consider how to minimize adverse effects to areas of cultural importance. Based on information collected to date, the Project would adversely impact cultural resources that are eligible for listing on the National Register of Historic Places. Potentially eligible cultural resources include prehistoric Native American sites and historic Euroamerican sites associated with ranching and agriculture or mining. Consultation with Native American Tribes and the State Historic Preservation officer will occur with respect to cultural resources impacts associated with this project. Native American Tribes will also be consulted regarding the presence of any traditional cultural properties that could potentially be affected by this project.
